Cynosphenodon (Script error: No such module "IPAc-en". Script error: No such module "Respell".; "Dog Sphenodontian") is an extinct genus of rhynchocephalian in the family Sphenodontidae from the Middle Jurassic La Boca Formation of Tamaulipas, Mexico. It is known from a largely complete lower jaw and fragments of the upper jaw. It is suggested to be among the closest known relatives of the tuatara, with both being placed in the Sphenodontinae,[1] which is supported by among other characters, the growth pattern of the teeth.[2]
